[Detailed description of the invention] This invention is a cooling cylinder in which an ice-shaving auger is rotatably arranged to scrape off ice that grows on the inner wall of the cooling cylinder. An upper bearing having a plurality of compression ribs protruding in the axial direction and extending in the axial direction and abutting against the inner wall of the cylinder is fixedly arranged, and the shaved ice is partitioned by the adjacent compression ribs, the peripheral surface of the bearing, and the inner wall of the cooling cylinder. To provide an improved compression passage for an auger type ice maker which makes chip ice by compressing it in the passage, especially for the purpose of making neat chip ice without cracks and improving the quality.

An embodiment of the present invention will be described below based on the drawings.

A shutter 15 electrically opens and closes the shutter.

Next, the compression passage 7 improved in the present invention
The shape will be explained in detail based on FIG. Three thick and long compression ribs 16 protrude from the circumferential surface of the upper bearing 6 at equal intervals in the radial direction and have a tapered surface 16A on the lower side surface, and three thin and short compression ribs 17 are formed between them. Further, an ice folding portion 18 is formed on the upper portion of the circumferential surface, and these portions are integrally formed with the upper bearing 6 . Furthermore, the lower part of the circumferential surface is formed into an inclined surface 19, and the upper part continuous with this is formed into a parallel surface 2 up to the ice breaking part 18.
It is formed to 0.

Then, the bearing 21 of the upper bearing 6 is inserted into the upper rotating shaft 5A of the auger 5, and screws (not shown) are screwed into the screw holes 22 formed on the outer surface of the compression rib 16 from the outside of the cooling cylinder 1. When the upper bearing 6 is fixed with
The outer surface of each compression rib 16, 17 is in contact with the inner wall of the cooling cylinder 1, and the inner wall of the cylinder 1, the adjacent compression rib 16
17, an inclined surface 19, and a parallel surface 20, six compression passages 7 are formed. In the lower part of the passage 7 , there is an ice compression passage 7 in which the depth between the inclined surface 19 and the inner wall of the cooling cylinder 1 gradually decreases upward.
A is formed, and the upper part has a parallel surface 20 and a cooling cylinder 1.
An ice regulating passage 7B is formed with equal distance from the inner wall of the cylinder 1 up to the upper end opening position. In addition,
In the embodiment, the inclined surface 19 and the parallel surface 20 are formed into curved surfaces, but they may be formed into flat surfaces.

Next, the operation of manufacturing chip ice cream will be explained based on the above configuration. As shown in FIG. 3, the ice containing moisture that has grown on the inner wall of the cooling cylinder 1 is scraped off by the auger 5 and transported upward to the ice compression passage 7.
At step A, it is gradually compressed to remove most of the moisture. Compression is substantially completed in this ice compression passage 7A, and the ice continues to enter the ice regulation passage 7B. This passage 7B is important for conditioning the compressed ice. That is, when the compressed ice passes through the ice regulating passage 7B, it is reformed into a well-arranged bar-shaped ice without any cracks. In this way, the compressed ice that has passed through the ice regulation passage 7B is shaped like a rod and extends upwards to the ice breaking section 18.
When it hits, an outward force is applied, and the chip ice 23 is broken at the opening edge of the cylinder 1 into a predetermined shape and transferred into the ice storage 10.

As described above, the present invention forms an inclined surface in which the circumferential surface of the upper bearing faces upward and gradually decreases the depth between the inner walls of the cooling cylinder, and the inner cylinder wall continues with the inclined surface and reaches the opening position of the upper end of the cooling cylinder. An ice compression passage and an ice regulation passage continuous to this are formed by forming an ice compression passage and an ice regulation passage that is continuous with the upper bearing, and an ice breaking part is formed integrally with the upper bearing at the upper part of the bearing circumferential surface, so that the compressed ice is This provides a practical advantage in that the chips can be folded into a substantially predetermined shape and provided with almost no cracks, and the quality can be improved.
